In this study, solvent extraction method has been utilized for separation of molybdenum and vanadium from nitrate solution by utilizing coupling of acid and solvating extractants (D2EHPA and TBP extractants). The outcomes demonstrated that synergistic solvent extraction improves stability of formatted complexes for transfer to the organic phase. The main parameters such as pH value, concentrati...

Oxime extractants 3-tert-butyl-2-hydroxy-5-methyl benzaldehyde oxime (HL1) and 3-tert-butyl-2-hydroxy-5-methoxy benzaldehyde oxime (HL2) were synthesized and characterized by conventional spectroscopic methods. Suitable lipophilic nature of the prepared extractants allowed examining the ability of these molecules for extr...

Modifiers have a broad array of influences on extraction with liquids in standard state, supercritical fluid extraction (SFE), trapping by SFE and supercritical fluid chromatography (SFC). They can significantly change the qualitative and quantitative results. Quantitative and qualitative results can be influenced by different extractants and modifiers in different ways as it was shown by Brond...

Alkyl-substituted phenolic pyrazoles such as 4-methyl-2-[5-(n-octyl)-1H-pyrazol-3-yl]phenol (L2H) are shown to function as Cu-extractants, having similar strength and selectivity over Fe(iii) to 5-nonylsalicylaldoxime which is a component of the commercially used ACORGA® solvent extraction reagents. Substitution in the phenol ring of the new extractants has a major effect on their strength, e.g...

Various extraction methods have been developed to assess metal bioavailability from sediments. In this study, we compared the extraction of Cd, Cr, and Zn from contaminated sediments using different extractants (normal seawater, acidic seawater of pH = 5. seawater with 1% sodium dodecyl sulfate [SDS], and gut digestive fluids collected in vitro from deposit-feeding peanut worm Sipunculus nudus)...

Pectin extracted from the apple pomace was evaluated for the in vitro inhibition of pancreatic lipase (steapsin). Pectin was extracted from two different varieties of apples, i.e., Malus pumila and Spondias dulcis using two extractants, i.e., hydrochloric acid and citric acid (CA), separately at pH 2.5. The effect of vailable online 12 May 2010

plant biomass harvested after heavy-metal phytoremediation must be considered as a hazardous waste that should be contained or treated appropriately before disposal or reuse. this study provides an evaluation of extractants for the removal of lead from abutilon theophrastus biomass. the research was carried out a leaching study to determine the lead-extraction efficiency of the different leacha...
